BGP table question...

I was just playing with IExperts Core Lab 4 and noticed something (not
specific to this lab). When you are passing eBGP-learned info to an
iBGP peer, do you pass the full table or just the "best" prefix that
was selected on the border router.

ASCII Visio's....

R2 (AS 200) <-----> R5 (AS 100) <----> R4 (AS 100)
R1 (AS 200) <-----> R5 (AS 100) <----> R4 (AS 100)

Basically if R5 is learning the same prefix from R1 and R2 (and they
are both showing up in the BGP table of R5), should he pass them both
to his iBGP peer R4 or just the best one?

Thanks in advance,
